Signs of Fall approaching as cool and wet hit Thornton

Updated Saturday, 8/16/08 @ 5:19am – Denver officially reached a high temperature of 59 degrees on Friday (Thornton reached 58).  This crushed the old record low maximum temperature of 68 degrees set in 1880.  Saturday has the potential to do the same with a forecast high of 56.

Updated Friday, 8/15/08 @ 2:25pm – A Flood Watch has been issued by the National Weather Service effective immediately through Sunday morning.  As always, keep up to date with our real time advisories and our NOAA All Hazards Radio system.


From a record setting heatwave just a couple of weeks ago to cool and wet and possibly record setting temperatures at the other end of the spectrum too!  Colorado is nothing if not inconsistent!  🙂

A closed low has developed over much of Colorado and temperatures have dropped considerably and rain has fallen over much of the Front Range.  Rain showers and isolated thunderstorms will dominate the weather Friday as will cool temperatures.  Friday’s forecast high of 62 degrees is in fact 24 degrees below normal for this date.  If that forecast holds true, we could set a record for the lowest high temperature for the date as well – the previous record is 69 degrees set in 1933!  The same holds true for Saturday as well with a forecast high the same as Friday and the lowest high temperature on record of 68 degrees set way back in 1874. 

The rain brings much needed moisture to the Front Range but it will be slow in falling and shouldn’t pose much in the way of flooding problems.  As of this writing, the Rocky Mountain Weather Network is showing pretty consistent precipitation across the metro area with 0.29″ having fallen at so far.  The moisture will be on and off through Saturday night and then begin decreasing Sunday and into Monday. 

It looks like the first part of next week we will return to more seasonal weather and temperatures into the 80’s.
